“If you believe that abortion is murder, and in capital punishment for murder, then what other position can you come to?”
Well, one big problem with this is “ex post facto”. You can’t apply a punishment retroactively to something that wasn’t a crime at the time it was committed. Abortion may be murder, but at this time, it is not “homicide”, as far as the laws and the courts are concerned. So, we cannot go back and apply any punishment to those who have committed the act, without violating our own long-held legal traditions.
If abortion was classed as homicide today, then we could talk about applying capital punishment in the future to someone who commits the act, but that is a different matter.
Good point.
